When RSA Data Security was acquired in the mid `90's they laid off a bunch of people, presumably to sweeten the deal, and security was waiting outside in the morning to block people from coming into the building.

One of my former colleagues, who showed up to work early, inadvertently freaked out one of the executives when they saw them in the hall. Naturally they (not the executive) were soon escorted out of the building and told they had been laid off.
